PRODUCTION OF METALLIC BODIES BY MEANS OF ELECTRODEPOSITIQN.

Toall whom, it may concern:

Be it known that I, STEFANO CONSIGLIERE,

engineer, of Genoa, Italy, having invented certain new and useful Improvements in the Production of Metallic Bodies by Means of -Electrodeposition, do hereby declare that the following is a full, clear, and exact being necessary that the surface of the proposed bodies be a regular one or one having a revolving surface.

The leading feature of the invention is the'employment of a suitable number of movable small bodies, which may be free or connected together in series according to requirements, preferably of spherical or rounded form, and hard, electrically nonconductors, and of suitable size and appreciable weight, such as glass or porcelain balls, ordinary pebbles, or the like, said bodies being put in continuous or inter- Initted movement inside the liquid of the bath, so as to beat and roll on the surface of the mold on which the metallic, layer is being deposited or has already been deposited, and all this with or without interruption of the electrical current. The move ment of said hard, relatively heavy bodies on the surface of the mold may be obtained in different ways, by means of rotation or oscillation, or a combination of rotation and oscillation of the vessel or drum con'taining the electrolytic bath, the object used as a mold (whose surface, in consequence of its nature or of a suitable preparation has electrically good conducting surface), being mounted inside the said vessel or drum, in which, besides the liquid of thebath, is placed a suitable quantity of said hard, relatively heavy and electrically non-conducting bodies, free or connected together in series. The said vessel or drum may thenv be set in rotation or oscillation on suitable bearings.

The mvention may be carried out in the Specification of Letters Patent.

apparatus illustrated in the accompanying drawings, in which-:

Figure 1 is a sectional view of said apparatus, the section being perpendicular to the axis of rotation; Fig. 2 is a front elevation; Fig. 3 isa section passing through the axis of rotation; Fig. 4 is a sectional elevation of the apparatus adapted to operate 7 on a different form of mold; Fig.5 is an enlarged elevation of the mold A partially sectioned in order to show the layer B of compact metal deposited on the surface of the mold and especially on the interiorof the tubes T. Fig. 6 is a plan view and sec tion of the said mold.

Like characters of reference indicate like parts throughout the views, in which:

A is the body or mold on whose surface the metalliccoating is to be applied by electro-deposition, which may be of such material that it may be totally or partially removed at theend of the process in order to produce hollow deposit metal bodies. 'If desired, more than one body or mold may be operated upon at the same time. B, B indicate the I hard, relatively heavy bodies, which maybe free or connected together in series which, during the continuous, or suitably interrupted, rotation or oscillation of the vessel or drum, in consequence of their rolling and beating on the surface ofthesaid mold, hammer or beat upon the metallic coating being deposited on the sur-.'

face of the mold A, or already deposited.

on it, rendering the said metallic coating more compact and resistant.

C, C are the anodes, constituted by the same metal that must be deposited on the surface of A.

D is the belt pulley by which the whole drum containing the bath is caused .to turntor oscillate on its bearings. .1 i

On the rings E and F are placed the brushes for the electric current; thecurrent enters the apparatus through the ring E, passes through the anodes C, C and through the liquid of the bath, reaches the-surface of the mold A, and from this, by means of' one or more conducting wires, goesto the ring F and consequently to the second brush upon the circuit being closed.

The journals may be;constructed hollow,

in order to permit the renewal of the liquidif the bath during the electro-deposition process, if required. Y 1

The form of the vessel or drum, as well as that ofthe anodes, may be' ofcourse very '5 different, according to the form of the mold A, though it is preferred to make it of prisinatic form, and various modifications may be made in'theconstruction of the apparatuswit'hout exceedingthe scope of the in- 10 vention. 7

Referring to Figs. 4-6 inclusive and particularly to Fi 4, .wherein a small multitubularboiler is-represented as being operated upon;the burnishing bodies 13 B con- 15 'nected in series work together with the loose bodies B, B like those of Fig. 1, and are employed especially to help the electrodeposition of a compact layer of metal on the surface of its internal tubes T, T, where the said loose burnishing bodies could not have as eflicient an action as on the other partsof the surface of the mold A. The said bodies B, B are strung in suitable number on metal wires W, W arranged be- '25 tween the two bottoms of the vessel in which .the el'ectro-deposition is carried on. The metal wires WV, W are preferably of the same material as the anode plates C, G, in order to aid the electro-deposition on the surfaces of the said internal tubes of the boiler. The Fig. 4 shows also the manner in which the mold A is maintained in a fixed position inside the vessel, by means of a rod S, one end of which is screwed to the body of the mold, and the other end to the wall V of the vessel. The said Figs. 4 to 6 illustrate away of using the burnishing bodies connected in series, but it will be under-' .stood that other similar connections may be .40 employed without departing-from the scope of the invention.
